Abstract

Arable soils located in the vicinity of urban and industrial area are considered vulnerable to heavy metals pollution.  Chemical inactivation, an in situ remediation method that used inexpensive chemicals to reduce pollutant solubility in polluted soil, was examined on a Cd-spiked arable soil. The study was aimed at to investigate the effectiveness of ameliorants and fertilizers normally recommended for crop cultivation, using tomato as the test plant, from the point of view to reduce soil Cd extractability and plant Cd concentration. A 100-day greenhouse experiment in completely randomized de­sign consisting of three rates of rationale dosage of ameliorants and fertilizers (RDAF) [0, 50, 100%] and four levels of soil Cd spike [0, 10, 20, 40 mg Cd kg-1 soil, using 3CdSO4.8H2O] in triplicate was conducted. The 100% rate of RDAF applied was: 4 ton dolomite ha-1, 30 ton cow dung ha-1, 150 kg N ha-1 (½ Urea + ½ Ammonium Sulfate), 150 kg P2O5 ha-1 (SP-36) and 100 kg K2O ha-1 (KCl). Significant reductions in soil extractable Cd (CdNH4OAc-EDTA) [from 13.35 to 8.77 mg kg-1, 34%] and plant shoots-Cd (Cdps) [from 8.66 to 5.46 μg g-1, 37%] were measured at 100% RDAF treatment as compared to the control soil, indicating the occurrence of an in situ soil Cd inactivation and plant element selective-uptake phenomenon. Multiple regression analysis that incorporating all 36 data pairs resulted in the following equations: (1) soil CdNH4OAc-EDTA = – 0.18 pHH2O + 0.21 PBray#1 + 0.51 organic-C – 0.57 exch.-Mg + 0.65 Cdaqua regia (R2 = 0.76), and (2) Cdps = 0.08 Nps – 0.17 Kps – 0.19 Mgps – 0.24 Pps + 0.27 Sps – 0.41 Caps (R2 = 0.54, 3 outliers removed). These results suggest that a proper amelioration and fertilization program may be prospective to be recommended as a low-cost Cd pollution remediation strategy for arable soils

Abstract

The dynamics and patterns of relationships between the characteristics of Indonesian tropical peat involving a function of time (ages of land use) in the context of land conversion have yet to be widely reported. The effects of tropical peatland use change are generally discussed regarding C emissions, with the limited literature identifying dynamic soil characteristics as these changes occur. This study used a survey method. We identified the physical, chemical, and C stock characteristics of peat in forest locations, oil palm plantations with a land use age of 0-5 years,>5-10 years,>10 years, and agricultural land with a land use age of 0-5 years and >5-10 years to find out the dynamics of soil characteristics. Land use changes from peat swamp forests to oil palm plantations and agricultural land, and the longer age of land use results in an increase in BD (especially at the top layer), ash content, pH, Total-N, total-P2O5, total-K2O, but there was a decrease in water content, fiber content, Organic-C, E400/E600, and soil C stocks. The alignment of economic, social, and ecological interests was directed to water and land management by regulating the area’s hydrological system and increasing peat stability.

Abstract

Ultisol is a weathered tropical soil order with low fertility status. It is also prone to nutrient leaching processes. Plantation area of PT. Great Giant Pineapple (PT GGP), grown in Ultisol, has been intensively cultivated for decades in rotation with banana and cassava. This study aims to evaluate the effects of FABA+compost amendment on nutrient leaching from the Ultisol in the PT GGP area and its implications for fertilizer management. A nutrient-leaching simulation was conducted using percolation experiments. Soil samples were taken from the 0-20 cm layer from pineapple-cultivated field plots 9 months after treatment application or 1 month before the plant regenerative-phase forcing step. Percolations were performed every 7 days with 170 mL Aquadest at 0.75 kg-1 soil for a 35-day experimental period, equivalent to the monthly average rainfall during the six wet months in the study area. The amelioration significantly reduced soil nutrient leaching, as indicated by tmax, total flux, and flux proportion. The band application of 25 t ha-1 FABA + compost gave the best results. The NO3 and K leaching flux proportions, however, were still high. It is suggested that controlled-release fertilizers be considered to reduce nutrient leaching flux.
